Alternative to TripIt = TripWaffle

[tripwaffle]

I don't use apple or gmail emails but outlook so had to sign up with my gmail. All the notifications from my friend's trip come to the gmail and I asked him to change it outlook but now I don't get anything. Is there a workaround or do I just need to keep checking gmail as well

If you go to Settings > Account and put your Outlook address in "Notification email". Everything we send will go there instead of Gmail.

Go to Settings > Email aliases and add your Outlook address there too:
tripwaffle.com/settings/email-aliases/

This will help with the trip your friend shared with you.

After that you can also sign in with your Outlook address using the email link option, and you'll land in the same account.

Any issues, feel free to hit the support option in the app.
